Lefty Leverenz commented on HIVE-10233:
---------------------------------------
Doc note: This adds two configuration parameters
(*hive.tez.enable.memory.manager* & *hive.hash.table.inflation.factor*) which
need to be documented in the wiki in Configuration Properties for release 1.3.0.
* *hive.tez.enable.memory.manager* belongs in [Configuration Properties -- Tez
|
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-Tez]
* *hive.hash.table.inflation.factor* belongs in [Configuration Properties --
Query and DDL Execution |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]
Is any general documentation needed for the memory manager? Perhaps in the
design docs?
* [Hive on Tez | https://cwiki.apache.org/confluence/display/Hive/Hive+on+Tez]
* [Hybrid Hybrid Grace Hash Join, v1.0 |
https://cwiki.apache.org/confluence/display/Hive/Hybrid+Hybrid+Grace+Hash+Join%2C+v1.0]
Also, this jira needs updates for Status, Resolution, and Fix Version.
